Earlier quoted context omitted.
It is completely reasonable to optimize for the vast majority typing 'mouse' and potentially misspelling it. Also "mousr petronics" shows up as the 1st choice in the autocomplete when typing "mousr". This is probably one of those products that can and should have its own website and sell from there or link directly to Amazon instead.
I don't think it's reasonable to show one thing when the user typed another. There are dozens of product results, there's no reason why one of the proper results wouldn't show up as well. "Results for Mousr ..." "Results for Mouse ..." etc
Seems more like poor naming on Mousr's part.
